IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 165,607, dated July 13,1875; application tiled April 2s, 1875.

To all whom it may concern:

Be it known that I, JAMus NAUGHTEN, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Door-Stop, ot' which the followingis a specification The object ot' my invention is to provide a stop orretaining device which, when applied to a door, will maintain the lattersecurely in any open position, and which will prevent it beingaccidentally closed or swung violently open or shut, while, at the sametime, the door maybe readily closed by hand. This stop consistsessentiallyT of a brush, pad, or yielding cushion, which is pressed downupon the carpet or iloor by the stress ot' a spiral or other suitablespring, the latter being coupled to the door in such a manner as to havea greater or less pressure imparted to it, as-occasion may require. Theattachment of the spring to the pad is preferably such as to permit theready coupling and uncoupling ot' the two, and serves to enable thesubstitution of a new spring, or one ot' less or greater tensionwhenever desired; and, furthermore, the stop is capable ot" beingadjusted horizontally toward or away from the door, and circularly, fora purpose which will be hereinafter fully described.

In the accompanying drawing, Figure 1 is a front elevation ot thepreferred arrangement of my doorstop, the circumferential guard of thepad being shown in section. Fig. 2 is a side elevation, showing saidstop applied to a door, the coupling devices being sectioned. Figs. 3,4, and 5 represent `modifications of my improvement.

In its preferred form, the stop or retaining device proper consists of acircular brush, A, whose head or stock B is of wood or other suitablematerial. This head has a circumferential groove, C, withinwhich issprung the lowermost coil ot' a spiral or helical spring, D, whoseuppermost coil terminates in a vertical stem or shank, E. This springhugs the head B so closely as to eftectually prevent any accidentalseparation of the two, while, at the same time, the brush may be readilyturned around within said lowermost coil, to correct any unequal wear.This mode of applying the spring to the head of the brush allows theready separation of the two whenever it becomes necessary to fit a newspring to the stop. The stem E of the tension springD, is inserted iuthe eye f of the horizontal member F of an angle-plate or bracket F F',whose vertical limb Fl is slotted longitudinally at f', for thereception of an ordinary wood-screw, G, and of a thumb-screw, H. Thesescrews, G and H, serve to imite said angle-bracket either to a block orplate I, or else directly to the door J. K K are wood-screws forsecuring the block or plate I to the door, whenever such a block orplate is employed, although its use is not essential. The pad AB iscoupled to the block I or to the door J, in the following manner L Lrepresent respectively the horizontal and vertical members of anangle-bracket slottedat l l', as more clearly shown in Fig. 2. Ot' theseslots, the one Z is traversed by an ordinary screw, M, and athumb-screw, N, while the other slot l has two screws O O passed throughit. The screws M and N enable the brush to be adjusted longitudinally ofthe slot l, so as to bring the brush in less or greater proximity to thedoor, as occasion may require. The object of such adjustment is toprevent the brush colliding with the carpet-strip P when the door isclosed. In case the brush should wear unevenly, the screw M can beretracted and the brush be rotated as tar as may be desired, after whichsaid brush may be secured to 'its new presentation by driving the screwM lagain into its head, so as to bring a new portion of the brush intoservice. The screws O O enable the brush to be set at any proper height,either upon the block I or upon the door J. In order to prevent thelowerlnost coil of the spring' coming in contact with the wall orskirting, or with any article of furniture when the door is opened, saidcoil is completely or partially surrounded with a sott guard or tender,R, that may be composed of rulber, ot' leather, or ot' other suitablemateria In the modiiication shown iu Fig. 3, the spring is representedas terminating at bottom with a spur, S, which is adapted to enter asocket T in the head B.

In the modification shown in Fig. 4, the tender R. is represented aslocated above the lowermost coil ot' the spring, and as being so as toIpreventany possibility-of thebracket meansfas to retain the ,door toany open posi- `.tion at which it may be placed, withoutfprehand; or, ifpreferred,-thefpressurefof-lthe said block in its proper position and`to tl1en` screw the retaining devices K K' intorthe door,

after havin g first inserted them iu the perforations i 'i'. Thisacthaving been accomplished, the bracket F F' is shifted downwardly, soas to compress the sp1ing`D,.aud to causethe brush A to bear upon thevcarpet or door with Y anydesired amount of pressure. lfhelproperpressure of f the .pad having lbeen .thus obtained, the .thumb-screwH-is then tightened,

F F shifting in either direction. i The: frictional contact ofY the `padory -bruslrwith .the carpet ory door is so adjustedby the above ventingtheintentional closureof the door by v-brusl1.1nay be partiallyor whollyrelaxed be- Vfore closing thedoor. vThe yielding nature of the spring Denables the brush A to pass over anyiuequalities or irregularities inthe floor or carpet without straining,` the stop or couplings;yorlinjury to the carpet.
